Details of the DICe algorithms
Hi DICe Team,
Thank you for the great open source DIC program! I just have a couple questions on some details about the algorithms.
-
Since I've only seen translation, rotation, shear and normal strains on the UI, does DICe only use the 1st order subset shape function?
-
Which gray level interpolation function is used?
-
Where can I find more information about the initialization methods we can select? How can we choose wisely according to our applications?
Thank you in advance!
Hi Wei-Meng515,
- There are second order polynomial shape functions available, but there isn't an option in the GUI to use them. You have to manually add a line to your params.xml file to use the second order shape functions:
<Parameter name="shape_function_type" type="string" value="QUADRATIC" /> - There are several available, KEYS_FOURTH is the default
- There isn't any documentation in particular for the initialization methods, but if you can describe your application I can help you choose the right one.

Can I have the full name of the KEYS_FOURTH method, so I can look into it.
